Industrial USB to 2-Ch RS485 Converter

This industrial USB to 2-channel RS485 converter adopts the original FT2232HL chip solution, providing stable communication with built-in galvanic isolation, lightningproof and anti-electrostatic protection. It is an ideal choice for industrial control equipment and applications with high communication requirements.

Key features

• Adopts original FT2232HL chip for fast, stable, and reliable communication with excellent compatibility
• Extends USB to 2-channel RS485, allowing concurrent and independent communication for each channel
• Onboard unibody power supply isolation provides stable isolated voltage, requiring no extra power supply for the isolated terminal
• Onboard unibody digital isolation enables signal isolation with high reliability, strong anti-interference, and low power consumption
• Onboard TVS (Transient Voltage Suppressor) effectively suppresses surge and transient spike voltage in the circuit – lightningproof and anti-electrostatic
• Onboard self-recovery fuse and protection diodes ensure stable current and voltage outputs, providing over-current/over-voltage protection and improved shock resistance
• Built-in 120Ω terminal resistor on the RS485 ports, configurable via jumper for flexible switching
• Three LEDs indicate power and transceiver status
• Industrial rail-mount ABS case design, compact, easy to install, and cost-effective

Wall-mount & rail-mount support

Industrial grade original chip solution

The original FT2232HL chip provides excellent stability and compatibility for industrial-grade performance.

Galvanic isolation design

• Onboard unibody power supply isolation provides stable isolated voltage, requiring no extra power supply for the isolated terminal.
• Onboard unibody digital isolation allows signal isolation with high reliability, strong anti-interference, and low power consumption.

Multiple protection, safe and stable

Onboard TVS (Transient Voltage Suppressor) effectively suppresses surge voltage and transient spikes in the circuit, providing lightningproof and ESD protection. The self-recovery fuse and protection diodes ensure stable current and voltage outputs, offering over-current/over-voltage protection and improved shock resistance.

Transmission distance up to 1.2km

The USB signal is converted into two balanced differential RS485 signals with stable transmission. The transmission distance is approximately 1.2km for RS485 and about 5m for USB.
